Back in bug #9993, we've started handling cases where kernel header
files that declare tracepoints/events/whatnot are incomplete (such
as due to missing declarations of function parameter types).  In
tapsets.cxx (tracepoint_extra_headers), we can opt to manually
include certain named kernel headers that complement the tracepoint
ones, which is useful if the kernel header goes unfixed. 

However, the code is not conditional on kernel configuration or version, so
for example for 2.6.33+ kvm tracepoints, <linux/kvm_host.h> is needed in
the "they_live" list.  However, this header does not exist on older kernels.
So we need to conditionalize the tracepoint_extra_headers() mechanism
(perhaps via individual runtime/autoconf-* tests), or find another type of
workaround for broken kernel headers.
